Description

风动地刷及其真空吸尘器
技术领域
本发明属于日用小家电制造技术领域， 具体地说， 涉及一种风动地刷及其空真吸 尘器。 背景技术
现在的吸尘器通常包括尘桶、 过滤组件和电机组件， 尘桶、 过滤组件和电机组件 位于一壳体内， 电机组件通过过滤组件与所述尘桶相连通。 电机组件包括电动机和风 扇， 当电动机通电后， 带动风扇叶片高速运转， 使吸尘器内部形成瞬间真空， 吸尘器 内部的气压大大低于外界的气压， 在这个气压差的作用下， 尘埃和脏东西随着气流沿 吸嘴和风道进入吸尘器的尘桶内， 再经过过滤组件的过滤， 尘垢留在过滤组件的集尘 袋内， 净化的空气则经过电动机重新进入室内， 起到冷却电动机、 净化空气的作用。 真空吸尘器利用其内置的电动机驱动风机而产生负压进行除尘， 它在操作使用时不会 灰尘飞扬， 并能吸除缝隙中及地毯上一般不易清除的尘屑， 使用方便、 操作简单， 被 广泛用于家庭和公共场所中。
在目前使用的真空吸尘器中， 真空吸尘器中风动地刷的结构有几种形式， 一种形 式如图 1所示， 含尘气流由地刷吸尘口进入滚刷室 1， 再由滚刷室 1进入涡轮室 2再 经过风道进入尘桶， 颗粒较大的灰尘和颗粒较小的灰尘全部要经过涡轮室 2， 针对上 述结构的风动地刷而言， 在涡轮室 2内， 如果涡轮室内壁和叶轮 4之间的间隙大， 则 叶轮负载能力差； 如果涡轮室内壁和叶轮 4之间的间隙小， 则颗粒较大的灰尘会卡死 叶轮。 在这种结构中， 没有清洁气流进入风道， 即含尘气流驱动涡轮旋转， 再由涡轮 旋转带动滚刷旋转。
如图 2所示， 还有一种风动地刷， 具有两个进气通道， 由吸尘口吸入的含尘气流 由滚刷室 1直接进入风道， 不经过涡轮室 2， 清洁气流由吸气口进入涡轮室， 由涡轮 室 2直接进入风道， 不经过滚刷室。 由于仅用清洁气流驱动涡轮旋转， 故该技术能解 决图 1中涡轮容易卡死问题。 由于经过涡轮室的气流直接进入风道 7， 没有带走灰尘， 这部分气流没有得到充分的利用。
在 "含有吸嘴主体的真空吸尘器" 中国专利 （专利号： 96110179.2) 中揭露了一 种地刷结构， 含尘气流是经过地刷吸尘口吸入滚刷室后， 再进入风道； 清洁气流从该 地刷中的涡轮进气口吸入， 吸入的气流供给涡轮产生转动力矩来驱动涡轮旋转， 与涡 轮安装在同一轴上的滚刷也被同时驱动旋转。 其中， 涡轮进气口吸入的清洁气流经过 涡轮室后再流入滚刷室， 使得该部分清洁气流还能携带灰尘进入风道， 即该清洁气流 在驱动涡轮旋转后还具有携带灰尘进入风道的功效。 但由于涡轮和滚刷是同轴设置， 涡轮不能做大， 从而存在负载能力差的缺陷。 发明内容
为了解决现有技术的不足， 本发明提供一种风动地刷， 所述风动地刷包括壳体、 滚刷和涡轮， 所述壳体设置有分别容纳所述滚刷的滚刷室和容纳所述涡轮的涡轮室， 所述涡轮驱动所述滚刷旋转， 含尘气流通过壳体设置的吸尘口进入所述滚刷室， 清洁 气流通过壳体设置的吸气口进入所述涡轮室，所述滚刷室和涡轮室之间设置引流通道， 流经涡轮室后的清洁气流通过所述引流通道进入所述滚刷室， 所述滚刷和所述涡轮不 同轴。
所述风动地刷还设置风道， 含尘气流从吸尘口进入滚刷室后进入风道； 清洁气流 从吸气口进入涡轮室， 通过引流通道进入滚刷室后， 再进入风道。 所述滚刷的轴线和 涡轮的轴线处于不同的水平面。
所述涡轮为径向风扇、 轴向风扇或混流风扇。
本发明还提供一种真空吸尘器， 所述包括吸尘器主体和风动地刷， 吸尘器主体和 风动地刷相连通， 吸尘器主体内设有电风机单元， 电风机单元作为真空发生器用于产 生抽吸力， 其中所述风动地刷为上述的风动地刷。
本发明解决了涡轮容易卡死或负载力差的问题， 又使得经过涡轮的气流得到充分 利用， 提高了清洁效率。 附图说明

如图 3所示， 本发明风动地刷在工作状态下， 含尘气流 6从吸尘口 9进入滚刷室 1后进入风道 7 ; 滚刷室和涡轮室之间设置引流通道， 清洁气流 5是从吸气口 8进入涡 轮室 2， 流经涡轮室 2后的清洁气流 5通过引流通道进入滚刷室 1， 最后进入风道 7， 这样经过涡轮室 2的清洁气流 5进入滚刷室 1时可以带走含尘气流 6中的灰尘， 使经 过涡轮室 2的清洁气流 5得到充分利用。涡轮可以是径向风扇、轴向风扇或混流风扇， 涡轮转动不需要含尘气流 6带动， 主要由进入滚刷室 1之前的清洁气流 5带动， 解决 了涡轮容易卡死的问题。 由于涡轮和滚刷不是同轴设置， 滚刷的轴线和涡轮的轴线处 于不同的水平面， 涡轮可以做大， 解决了负载能力差的缺陷， 还有利于风道的顺畅。 另外， 涡轮的轴线和滚刷的轴线可处于不同的水平面， 涡轮轴线位于滚刷轴线上部， 如图 3所示。 当滚刷的轴线和涡轮轴线处于不同的水平面时， 有利于涡轮室和滚刷室 的设置， 可以充分利用地刷的内部空间， 减少地刷的表面积。
图 4为本发明直立式真空吸尘器立体图， 如图 4所示， 本发明提供一种具有灰尘 分离功能的真空吸尘器 100， 该真空吸尘器 100包括吸尘器主体 101和风动地刷 130， 该吸尘器主体 101设置有电风机单元（图中未示）， 电风机单元作为真空发生器用于产 生抽吸力。 风动地刷 130与吸尘器主体 101相连通， 用于从待清洁表面吸入带有灰尘 的空气。 真空吸尘器 100包括旋风分离装置 102， 该旋风分离装置 102安装在吸尘器 主体 101上， 其与吸尘器主体 101和风动地刷 130相连通， 用于实现气固分离， 干净 的气流通过电风机单元的出口释放到大气中。 当灰尘颗粒集满后， 使用者可以将旋风 分离装置 102从吸尘器主体 101上取出， 实现倒灰功能。
